Just a quick one really
Take something like a 2N3904 transistor. A small signal NPN transistor.
The Ptot is given as 625 mW at Tc 25C.
When considering Ptot does this include the power dissipation of the CE and the BE collectively or just the CE?
Adjustments for heat sinks and ambient temperature apart, is there a good practice when it comes to picking a transistor with an appropriate Ptot?
What I mean is if your circuit demand turns out to be nW do you double it? Treble it?
Thanks
